Introduction and Ari’s background in the military and aerospace industry
What is a Hardware-in-the-Loop testing and the inspiration behind it
- Taking a costly testing infrastructure to the comfort of your home lab
- Headstart up to 75% of your board testing
The problem around the prevailing way of designing and testing—retesting every step of the way using expensive testing equipment, and takes more time for your design engineer, plus the back and forth can blow up your cost quickly
The importance of designing and testing simultaneously and proactively—design engineers have to be part of the test process
The impact of Covid-19 on product development and testing
The need for software-based approach to the hardware development design
Maker movement and hobbyist around the world contributes to less expensive and accessible test solutions (plug-and-play)
Design board, prototype, and watch it fail
- Rework the board
- Run test in 3 minutes in couple hundreds of bucks
Ari explains how the software in the embedded system works
Ari shares complete details of automated low-cost testing in his article: Low-Cost Solutions for Automated Hardware-in-the-Loop Testing
- The concept is to use a simple device that can drive analog signals, read analog signals, generate various protocol serial streams, and analyze waveforms.
